Dear Mr Bachman,
On another forum I have seen another post stateing that the K has the wrong gear ratios in the gear box.
My question is why did Bachman use a 14 to 1 ratio in the Kay instead instead of say a 29 to 1 ratio.
Thanks, Chuck
Dear Chuck,
Not being involved with gear btarin design, I have no idea why one was chosen over the other. I believe the Mallet is 1:28, though...
Have fun!

Any chance the new articulated gears could be used to replace the K's?

Dear Bach-man,
I was told to ask you this question, so here I go....
Why did Bachmann choose the 28.1 ratio for the Mallet vs. the 14.x for the K?
thanks and Merry Christmas!

Dear Cale,
The Mallet uses a different motor, and it was felt that this was the best ratio for this model/ motor combination.
Happy Holidays!

thanks!, any word on what motors were used this time?
ikydvl,
The K-27 gearbox is very unique. The axles are very large with inserts to allow the axles (all four ) to slide sideways, both directions. The driven gear on the third axle is extra large. Any new motive power would have to use the existing axle gearing. The 2-6-6-2 appears to be more conventionally arranged; two vertical motors, small gearbox......seems similar to the Cinnie setup, with a better motor and gearbox.
I am working on a mod for the K-27, it's got the right motor, it just needs the right gear ratio. I'll keep everyone posted......but the Connie gearbox and motor come first.
